RAIL-FASTENING.

Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed August 6, 1913. Serial No. 783,303.

To all whom it may concern:

Be it known that I, JOHN S. MILLER, a British subject, residing at Truro, in the county of Golchester, in the Province of Nova Scotia and Dominion of Canada, have invented new and useful Improvements in Rail-Fastenings, of which the following is a specification.

My invention relates to fastenings for securing railroad rails on to the cross ties, especially ties made of concrete, and the object of my invention is to provide a durable, simple, cheap and effective fastening. I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a tie adapted to the reception of my invention with the inset O in position. Fig. 2 is an enlarged vertical section on line a b of Fig. 1 showing a rail and the fastening in position. Fig. 3 is a section on line 0 d of Fig. 1. Fig. 4 is an edge view of the key. Fig. 5 is a side view of the same. Fig. 6 is an edge view of the dovetailed rail holder. Fig. 7 is a side view of the same. Fig. 8 is a plan of a plate resting over the inset C. Fig. 9 is an-edge view of the same.

Similar letters refer to similar parts throughout the different views.

A is a railroad tie made of concrete, and reinforcing bars and inclosing the inset C which is a single casting having dovetailed iecesses for the reception of rail holders and eys.

a a are longitudinal looped reinforcing bars. 5 b are reinforcing loops inclosing said longitudinal bars.

B is the rail.

6 is a metal plate between the rail and said inset having openings corresponding to the recesses in said inset; this plate is especially applicable in the use of ships or liners for vertically adjusting the rail as always being in contact with the rail it is in a position to receive the strain incident to driving the keys shown in Figs. 4 and 5, and by extending beyond the inset it forms a fulcrum for the bar in drawing the keys and protects the concrete from damage by the use of the 0 0 are dovetailed rail holders which are formed with a strong head on one edge for the purpose of clasping the rail flange. They are transversely parallel but are longitludicpally wider at the bottom than under the d cl are ordinary headed keys tapered longitudinally but transversely parallel.

The rail holders 0 0 and the keys d (Z have no special looks, or checksof any description to engage with corresponding checks in the inset but are designed to admit of vertical rail adjustment.

The method of using the rail fastener is to insert the dovetailed rail holder through the plate 6 into the recess in the inset with its head clasping the rail flange and force it into a holding position by the keys d d as shown.

The slots m can be enlarged so as to take wood or metal shims if desirable.

Having described and illustrated my invention what I claim and desire to secure by patent is,-

The combination of a tie, a metallic insert formed of a single piece of material and embedded in the tie including spaced sockets connected by a relatively thin web, the adj acent walls of the spaced sockets converging downwardly to the bottom of the tie whereby the sockets are wider at their lower ends than at their upper ends, a plate having apertures coinciding with the sockets of said insert, a rail on said plate between the apertures thereof, rail engaging elements fitted in each alining aperture and socket and having an inclined side fitting the diverging wall of the respective socket, and keys interposed between the rail engaging elements and the adjacent walls of the socket.
